Re: [Xen-users] debian lenny 3.2.1 doesn't boot, livexen boots just fine

["jpp@xxxxxxxxxxxxxxxxxx" <jpp@xxxxxxxxxxxxxxxxxx>]

Hello,

The syntax is not the same in GRUB2 example :
"old" grub.cfg style :

menuentry "Debian GNU/Linux, with Linux xen" {
        insmod ext2
        set root=(hd0,1)
        search --no-floppy --fs-uuid --set 116c3b30-4586-4f25-b7c1-c0d5c5a5b003
        kernel  /xen.gz dom0_mem=1536M
        module  //vmlinuz-xen root=UUID=bc847804-e4d5-49d0-b6ff-998886cbf9b2 ro
noquiet
        module  //initrd-xen
}


"New" grub.cfg style :

menuentry "Debian GNU/Linux, with Linux xen 3.4.3-rc2" {
        insmod ext2
        set root=(hd0,1)
        search --no-floppy --fs-uuid --set
116c3b30-4586-4f25-b7c1-c0d5c5a5b003
        multiboot       /xen-3.4.gz /xen-3.4.gz noreboot dom0_mem=3072M
cpufreq=xen cpuidle
        module  /vmlinuz-2.6.31.4-xen /vmlinuz-2.6.31.4-xen
root=/dev/md0 ro  noquiet
        module  /initrd.img-2.6.31.4-xen  /initrd.img-2.6.31.4-xen
}

You have to use "multiboot" ... and module the new (?) syntax.

For "standard" kernels the syntax has not changed :

menuentry "Debian GNU/Linux, avec Linux 2.6.32" {
        insmod ext2
        set root=(hd0,1)
        search --no-floppy --fs-uuid --set 116c3b30-4586-4f25-b7c1-c0d5c5a5b003
        linux   //vmlinuz-2.6.32 root=UUID=bc847804-e4d5-49d0-b6ff-998886cbf9b2
ro  noquiet
        initrd  //initrd.img-2.6.32
}
